Use Python for data analysis: This book is a detailed version of Python's pandas package. Learn this to master some basic pandas commands. However, this is not the point, because pandas is too slow to produce a large amount of data and may collapse (I don't know if there is any improvement now-!) The point is, through studying this book, I feel a little about the data operation and am familiar with the basic data operation process. All the operations in this book can be replaced by native Python, and Pandas package is not needed. Finding feelings is very important.

Some recent systems basically default to 1024 bytes of backlog size, but many servers on the network configure it to 128 bytes or less. Usually, the time threshold for retransmitting SYN-ACK is 5 seconds, which is twice the normal successful reception time. The default timeout time is 3 seconds, and the time from the first SYN-ACK to its TCB being recovered is 189 seconds.

4. There are no new varieties of lobsters at present, but crayfish grow differently in different regions. Shrimps are generally imported from the local area. In this way, lobsters do not undergo long-distance transportation, but also adapt to the local geographical conditions and are easy to survive. Where did the seedlings come from? Many people asked for seedlings online. First of all, do you have crayfish in your area?

From April to May, the number of wild crayfish is very large, Find a shrimp dealer in the street, Let them help you collect, you can choose small specifications, so the price is cheap, small specifications dealers generally can't sell a good price, generally can buy around 5 yuan, of course, this depends on the local actual situation, if there is no local crayfish, shrimp seedlings are not in demand and worthless, more breeding is a little more popular. It is also easy to collect tens of hundreds of catties every morning, Generally, a kilo of 50-200 tails is good, On the same day, it will be transported back to the pond after simple disinfection. It will put about 100kg per mu. After putting it in, it will usually die. Dead shrimps will often be salvaged. Remember to repair the seedlings if you die. No matter whether you bought it from other places or someone else's pond, you will always die if you put it back. If you buy it locally, the price will be low and the cost of dying will not increase much.
